  • pH measurement: Six technical tips

    The pH value is one of the most important and therefore also one of the most frequently measured quantities in analytical chemistry. Sometimes, a simple pH test strip is sufficient for making a rapid check; precise pH meters are, however, required whenever accurate measuring results are needed. Such a pH meter is available in nearly every laboratory and is generally ready for use at a moment's ...

  • Application of PTFE membrane for ammonia removal in a membrane contactor

    The feasibility of a membrane contactor system for ammonia removal was studied. The mass transfer coefficient was used to quantitatively compare the effect of various operation conditions on ammonia removal efficiency. Effective removal of ammonia was possible with a Polytetrafluoroethylene (PTFE) membrane contactor system at all tested conditions. Among the various operation parameters, contact ...

  • Aqua magazine features quotes from ITS Vice President

    Testing water seems like it should be quick and easy. You just dip a strip anywhere in the pool water and read, right? Wrong. If you’re giving your customers the best service you can, you know it’s not that simple. In fact, there are a number of critical factors to keep in mind as you test pool water, so with the help of a few industry experts, AQUA has compiled a list of 10 water ...

  • ITS marketing manager quoted in WaterTech

    Professional, ethical testing will start you off on the right foot and will directly determine which services the customer may need. Many substances could be in a customer’s water, but, “It’s not necessary to test for every parameter; that’s what labs are for,” advises Rob Samborn, director of sales and marketing for HM Digital, a Los Angeles-based maker of water ...

  • Systematic model development for partial nitrification of landfill leachate in a SBR

    This study deals with partial nitrification in a sequencing batch reactor (PN-SBR) treating raw urban landfill leachate. In order to enhance process insight (e.g. quantify interactions between aeration, CO2 stripping, alkalinity, pH, nitrification kinetics), a mathematical model has been set up. Following a systematic procedure, the model was successfully constructed, calibrated and validated ...

  • Treatment of wastewater from a low-temperature carbonization process industry through biological and chemical oxidation processes for recycle/reuse: a case study

    Low-temperature carbonization (LTC) of coal generates highly complex wastewater warranting stringent treatment. Developing a techno-economically viable treatment facility for such wastewaters is a challenging task. The paper discusses a case study pertaining to an existing non-performing effluent treatment plant (ETP). The existing ETP comprising an ammonia stripper followed by a single stage ...

  • Phosphorus release risk on a calcareous purple soil in southwest China

    Growing concerns about water eutrophication made it imperative to control phosphorus (P) losses from agricultural soil to water. A Quantity-Intensity (Q-I) relationship that reflects the potential of soil P release to water was developed on the calcareous purple soil in southwestern China. Results showed that a change point appeared at 30 mg kg−1 for Olsen-P and 22 mg kg−1 for iron-oxide ...

  • Strategies to optimize phosphate removal from industrial anaerobic effluents by magnesium ammonium phosphate (MAP) production

    Owing to more stringent phosphate discharge requirements and the increasing prices of fertilizers, beneficial recovery and reuse of phosphate from industrial anaerobic effluents is becoming an important issue. Phosphate recovery by struvite or magnesium ammonium phosphate (MAP) permits its recycling in the fertilizer industry because struvite is a valuable slow release fertilizer. Two different ...


  • Flame Retardancy of Thermoplastic Polyurethane and Polyvinyl Chloride by Organoclays

    Thermooxidative stability and peak of heat release rates of thermoplastic polyurethane nanocomposites are improved by organoclays; but time to ignition of these composites is reduced.
